A)7.01% H and 92.99% O B)7.22% H and 92.78% O C)6.32% H and 93.68% O Here at the One Minute Miracle blog, our focus is to provide our readers and customers with a wealth of resources that will empower them to make smart decisions about the responsible use of food grade hydrogen peroxide products. The concentration of KMNO4 is 1.02 x 10^-3 mol/g solution . Hydrogen peroxide does not remove ear wax, though. Hydrogen peroxide has the chemical formula H2O2. Determine the percent H2O2 in the solution through a titration with KMNO4 solution. For example: (i) Synthesis of ammonia: A mixture ofN 2 and H 2 in the ratio of 1:3 compressed to 200 atmospheres and heated to 673 K in the presence of a catalyst is used for the manufacture of ammonia in Haber's process. 0 0. Oxiclean is reputed to be composed of about 60% sodium percarbonate. Studies conducted in 1940s by Father Richard Willhelm, pioneer in promoting hydrogen peroxide, have revealed that it can be used to treat several ailments, right from bacterial-related mental illness to even polio. HINT: The density of hydrogen peroxide is 1.02 g/mL. Need to calculate the percent by mass of hydrogen peroxide in a sample given.
